Buddy-Photo of Leg-Is this normal?

I'm worried about his leg. It's a lot more red than it was yesterday. I don't think the first one looked like this or I would have record of asking this back then. I tried to take a picture but I can't spread the leg far enough to get to the underside. The part where my fingertips are is the worst. More of an area and more red than the part you can see. What do you think? He's on antibiotics. Does this look infected or am I just overreacting?

Oh! Poor Buddy. and poor Mom. That looks so sore. I feel like I want to get down on the floor and hug Buddy. I am sure that Hershey Kisses would like to share some kisses and help that leg feel better.
